Apple claims the first week of January set a new record for App Store revenue – over half a billion dollars has been spent on apps and in-app purchases so far – and New Year’s Day 2015 saw the biggest number of apps sold in a single day ever. App Store developers have earned a cumulative $25 billion from the sale of apps and games, Apple said.

That’s the environment we find ourselves in as Apple enters 2015, a year in which developers have a reasonable chance to make a lot of cash developing for iOS.

Apple’s keeping the furnace nicely stoked, of course. Expectation of a 12.9-inch iPad, an iPhone 6S, even the Apple Watch (or Apple TV) will open new developer frontiers. And will the new MacBook Air run both OS X and iOS? Even the speculation ignites interest in Apple’s platforms.

The main competing mobile platforms simply don’t match the App Store advantage, driving developers to focus on the Apple platform. This feeds back into the platform, giving the company good feedback with which to improve its offer.

Action and reaction

Meanwhile it looks like people are beginning to understand that Android is a compromised choice: around 18% of iPhone 6 customers are switching to iOS from Android. "Android fatigue is setting in," Neil Mawston, Strategy Analytics analyst told CNBC.

So, what does this mean?

‘Tremendous start’

It means that as Apple makes its long-planned iPhone 6-led grab to regain ground lost since its close partners became its competitors, it will see its market share grow. As its share grows, the activity levels of the user base will grow, developers will sell more apps and the momentum will continue to build.
